This was a lot of work. There were some things that were left out in the final timelapse build video that are explained in the individual parts of this build (mainly parts 5-10). So if you are watching and notice that I switched carb setups and turbo's, watch those earlier videos, they are more in depth and I explain what I'm doing. The bike runs great now (though it does burn oil because of the draw-through turbo setup) and makes a full 12 PSI of boost! Below are links for all of the parts I used, from the turbo setup to the electronics.
